Daily maintenance of cone crusher: pay attention to adjust the discharge clearance frequently. With the accumulation of crushing time, the wear of crushing lining plate will increase, the particle size of crushing products will change, and the crushing power consumption will also increase. Therefore, adjust the discharge clearance frequently and keep it within an appropriate range to make the crusher always have a good crushing effect. The lubrication of cone crusher is mainly to prevent the wear of key moving pairs such as moving cone and its support seat, main shaft and shaft sleeve. Select appropriate lubricating oil to ensure appropriate oil pressure and oil supply; Fill lubricant regularly and quantitatively to prevent water and dust from polluting the lubricating parts; The lubricant shall be replaced in time after a certain period of use or deterioration.
What should we pay attention to in the multi cylinder hydraulic cone breaking load test? 1) The time of load test and half load test shall be in accordance with the provisions of technical requirements; 2) During the load test, measure whether the current of the main motor has abnormal fluctuation; 3) During the load test, the feeding shall be uniform and observe whether the discharge is smooth; 4) Observe the values displayed on the inlet oil temperature gauge and return oil temperature gauge on the lubrication station; Check the clearance between the pinion and the frame by pressing the eccentric sleeve. When checking the axial clearance of the transmission shaft, put the back of the pinion against the end face of the transmission shaft bushing, and check the clearance between the oil slinger and the other end face of the transmission shaft bushing with a feeler gauge.
Maintenance of main parts of cone breaking: maintenance of eccentric parts, which is composed of eccentric shaft, conical vertical shaft bushing and cylindrical eccentric sleeve. The eccentric shaft shall be flexibly assembled in the bronze or Babbitt alloy eccentric bushing of the machine body, and the conical vertical shaft shall also be flexibly assembled in the conical vertical shaft bushing on the eccentric shaft. Due to wear, the increased clearance of working parts of crusher shall not exceed 1.5 times of the normal clearance. During maintenance, the fit between the cylindrical eccentric shaft bushing and the eccentric shaft bushing hole on the machine body must be checked. When the shaft sleeve is too loose, it must be repaired, adjusted or replaced in time.
